BORING AND ROUTING MACHINE.

i ,acceso Application lerl August 15, 1919.

To all whom t may concer-n.'

Be it known that I, DANIEL S. Sco'r'r, a citizen of the United States,residinor at Baltimore, in the State of Maryland, ave invented certainnew and useful Improvements in Boring and Routing Machines; and I dohereby declare the following to be a full, clear, and exact descriptionot the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

My invention relates to boring and routing machines. The object oi myinvention is to provide a portable prime mover, such as an electricmotor with detachable mechanisms, one of which can be used for boringholes and the other of: which can be used for routing. A further objectoi my invention is to provide the mechanism for routing with suitablegages so that the path of the routing cutter may be determined thereby.

In the drawings Figure 1 is a side elevation of an electric motor,showing my improved routing inachinc detachably secured thereto, therouting machine being shown in section.

Fig. 2 is a view of the routing machine shown in Fig. 1, when viewed inthe direction of the arrow 2 in said figure, the cutter being omittedfor the sake of clearance.

Fig. 3 is a sectional view of the boring mechanism, the locking pawlsbeing omitted for the sake of clearance.

Fig. 4 is a view of the locking pawls and locking pins, when viewed inthe direction of the arrow et in Fig.` 2.

In the drawings, represents an electric motor which may be of anyimproved design, and it is preferably provided with a handle l1. rlhemotor 10 is provided with a sleeve 12 and in the latter there aresecured locking pins 13--13- The shaft 14 of the motorextends throughthe sleeve 12 and terminates in a square end 15.

My improved routing mechanism consists of the casing 16 provided with asleeve 17 which fits snugly upon the sleeveV 12 and is provided withright angle 'slots 18-18 for the reception of the locking pins 13-13-The locking pawls ,19--19 are pivotally secured upon the sleeve 17 bythe screws 20-20- The casing 16 is provided wit a bottom 21 securedthereto in any improved manner, and said casing and bottom are each andthe roller is Specification of Letters Patent. i Patented J 3,11, 25,192L Serial No. 317,652,

provided with bosses, in which are cylindrical bearings for thereception oi' the bearing portions 22H22 of the bevel gear 23. Thebearing portions 22-22 are provided with a central square hole 24 forthe reception of the squared end 15. rlhe casing 16 is provided with asleeve 25 in which is revolubly mounted the shaft- 26, upon one end ci?which is secured the bevel gear 27 which meshes with the bevel gear 23,and upon the other end of which is secured the routing cutter 28. Thegage rollers 29 and 30 are slidably secured upon the casing 1G by thescrews 31-31, the roller 29 being adjustable in a vertical plane and theroller 30 being adjustable in a horizontal plane.

The casing 16 is also provided with a handle 32.

The operation of my improved 'routing machine is as .ollows`:

The free ends of the locking pawls 1919 are to be moved upwardly untilthe bodies of the pawls clear the slots 18-18; the sleeve 12 is then tobe introduced into the sleeve 17 and the pins 13-13 introduced into theslots .18-18. The sleeve 12 is to be pushed in until it occupies theposition shown in Fig. 1. During this operation, the cutter 28 is to berevolved until the hole 24 is in proper alinernent with the squared end15. lhen the pins 12B-13 reach the bottom oi' the vertical portion ofthe slots 18%18, then the motor is to be turned in a clockwise directionbringing the pin 18-13 to the ends of the horizontal portions of saidslots. The locking pawls 19-19 are then to be moved to the positionshown in Figs. 1 and 2, thus preventing disengagement of the pins 13-13from the slots 18-18- The roller 29 is then to be set to determine theproper depth of cut to be made by the cutter 28 in the work to be set todetermine the location at which said cut is to be made. The operatorthen grasps the handles 11 and 32, and applies the cutters to the work.v

` My improved drilling mechanism consists of the drill chuck 34; whichis secured upon the shaft 35, the latter being provided with a squarehole 36 and a groove 37, in the latter of' which the point of the screw38 lis in* troduced and serves to prevent displacement of the shaft withreference to the sleeve 39. The sleeve 39 is provided with a handle 40,and with slots similar to the slots 18--1S.

' guide the drill While Vit is at Work.

yDrillscan then be introduced in the drill chuck 34 and the operatorapplying his hands to the handles ll and 4() can? then Thus it will beseen that I provide a simple, cheap and eilicient boring and routingmachine which can be variety of uses.

applied to a Wide l. The combination With a motor, including a drivingshaft, of a sleeve thereupon, pins in said sleeve, a second sleevemounted upon- Saidrfirst named sleeve and hai/'ing slots engaging saidpins, a routing machine supported by said KVsecond 'sleeve and includinge gear provided With a square driving hole and a square on said shaftengaging Vsaid hole'. i

2. In a routing machine, the combination with a casing and fixedbearings in Said cesing, of a cutter revolublysupported in saidbearings, a gage adjustably secured to said casing for limiting thedepth of cut made by said Glitter and a Second gage edjustably securedto said casing for determining the location of said out.

In testimony whereof I ailix my signature.

DANIEL S, SCOTT.
